Description

Superheated steam generating device

The invention relates to a superheated steam generating device which generates superheated steam.

As such a superheated water vapor generation device, for example, as shown in Patent Document 1 (Japanese Patent Laid-Open Publication No. 2006-226561), a saturated water vapor generation unit that heats water to generate saturated water vapor is provided, and the saturation A superheated steam generating section that generates superheated steam by heating water vapor.

The superheated steam generated by such a superheated steam generating device is used, for example, to sterilize a container before filling food or to heat food in a restaurant or the like.

However, in the conventional superheated steam generating device, even if a relatively efficient induction heating method is used as a heating means, it takes about 20 minutes to generate 700 ° C superheated steam from normal temperature water, for example. In other words, it is necessary to wait for the above-mentioned time from the start of the use of superheated steam to generate superheated steam, so that, for example, in a restaurant or the like, the service provision time is delayed, and the customer demand cannot be met.

On the other hand, if the device is continuously operated and superheated steam is continuously generated, although the above-mentioned waiting time is not generated, superheated water is not required. During the steam, the continuous consumption of energy causes waste.

In order to solve the above-mentioned problems, the present invention mainly provides a superheated steam generating device capable of generating superheated steam in a short time and suppressing energy consumption.

That is, the superheated water vapor generation device of the present invention includes: a water vapor generation section, the water vapor generation section of the induction heating method or the energization heating method generates water vapor from water; the superheated water vapor generation section, the induction heating method or the energization heating method The superheated water vapor generation unit is supplied with water vapor generated by the water vapor generation unit to generate superheated water vapor from the water vapor; and a switching mechanism is provided in the water vapor generation unit and the superheated water vapor generation unit. Between the units, the supply or stop of the supply of the water vapor to the superheated steam generation unit is switched, the supply or the stop of the supply of the water vapor is switched by the switching mechanism, and the superheated steam generation device is switched from a standby state In the supply state, the standby state is a state in which the water vapor generation unit generates water vapor and the supply of the water vapor is stopped, and the supply state is a state in which water vapor is supplied to the superheated water vapor generation unit.

According to this superheated water vapor generating device, since the water vapor generating unit generates water vapor in advance in a standby state before switching to the supply state, it is possible to shorten the time until superheated water vapor is generated and the time until water vapor is generated from the water. Superheated steam can be generated in a shorter time than before.

More specifically, a case where superheated steam at 700 ° C. is generated will be described. At this time, the heat of generating saturated steam at 130 ° C from water at normal temperature accounts for 2/3 of the total amount of heat generating superheated steam at 700 ° C. Thus, according to the above The superheated water vapor generating device can generate 130 ° C saturated water vapor in the water vapor generating section in the standby state in advance. Therefore, by switching from the standby state to the supply state, it is possible to generate 700 ° C in seconds to minutes. Superheated steam.

In addition, since the supply of water vapor is stopped in the standby state, the water vapor generation unit does not have to continuously generate water vapor, thereby suppressing the energy consumed in the standby state, thereby enabling energy saving.

In addition, when energy saving is achieved, as the energy consumed in the standby state, for example, in order to supplement the heat emitted from the water vapor generating section and the superheated water vapor generating section, the water vapor generating section and the superheated water vapor generating section are supplemented with heat. The amount of heat and the like is provided.

Here, when the water vapor generated by the water vapor generating section increases sharply and flows into the superheated water vapor generating section waiting in a high temperature state, the superheated water vapor generating section may be damaged by thermal shock or the life may be reduced.

Here, preferably, the switching mechanism is an on-off valve, and the superheated steam generating device further includes a valve control unit that controls the on-off valve, and the on-off valve is gradually opened from a closed state by the valve control unit. At a predetermined valve opening degree, the superheated steam generating device is switched from the standby state to the supply state.

In this way, since the water vapor is gradually supplied to the superheated water vapor generation unit from the time when the standby state is switched to the supply state, the thermal shock caused by the rapid increase of water vapor and a large amount flowing into the superheated water vapor generation unit can be reduced as described above.

Preferably, the switching mechanism is provided in the water vapor generating section and A pressure regulating valve between the superheated water vapor generating unit, and the superheated water vapor generating device further includes a valve control unit that controls the pressure regulating valve, and the valve control unit controls the pressure regulating valve, and the overheating The water vapor generation device is switched from the standby state to the supply state, and adjusts the pressure of the water vapor supplied to the superheated water vapor generation unit.

In this way, if the pressure of the water vapor supplied to the superheated steam generation unit is made zero, the standby state is established, and the pressure is gradually increased from the standby state to switch to the supply state. Therefore, the pressure regulating valve can perform the function of the on-off valve and adjust the pressure of water vapor, so that one valve can have the functions of opening and closing and regulating the pressure.

Preferably, it further includes a temperature control unit that controls a heating temperature of the superheated water vapor generation unit and a heating temperature of the water vapor generation unit. In the standby state, the temperature control unit converts the superheated water vapor The heating temperature of the generating section is controlled to a temperature higher than the heating temperature of the water vapor generating section.

The heating temperature referred to herein is, for example, a set temperature of a heating means for inductively heating or energizing heating a heating conductor tube or the like through which a fluid flows, or a temperature of the heating conductor tube itself.

In this way, the water vapor generated by the water vapor generation unit is heated immediately after being supplied to the superheated water vapor generation unit, so that the superheated water vapor can be generated in a shorter time.

Preferably, in the standby state, the temperature control unit controls a heating temperature of the superheated steam generation unit based on the temperature of the superheated steam generation unit, and in the supply state, the temperature control unit The heating temperature of the superheated steam generating section is controlled based on the temperature of the superheated steam.

In this way, the temperature of the superheated steam generation unit may be maintained at a desired temperature in a standby state where no steam is present in the superheated steam generation unit. In addition, since the heating temperature of the superheated steam generating section is controlled in accordance with the temperature of the superheated steam in the supply state, it is possible to ensure generation of superheated steam at a desired temperature.

Preferably, after a predetermined time has elapsed from the moment when the superheated steam generating device is switched from the standby state to the supply state, the temperature control unit is configured to control a heating temperature of the superheated steam generation unit. , The temperature of the superheated steam generation unit is switched to the temperature of the superheated steam.

In this way, the temperature for controlling the heating temperature of the superheated steam generation unit can be switched from the temperature of the superheated steam generation unit to the temperature of the superheated steam at the timing of superheated steam generation in the supply state.

Here, in order to bring the superheated steam to a desired temperature, the superheated steam generating unit in the supply state is supplied with a large amount of electric power and maintained at a high temperature. Therefore, if the superheated steam generation unit is switched from the supply state to the standby state while the superheated steam generation unit is maintained at a high temperature, the superheated steam generation unit will reach a temperature higher than the set temperature in the standby state, and thus the specifications of the device in the supply state There is a danger of damage to the device due to operation near the maximum temperature.

Therefore, it is preferable to stop supplying water vapor to the superheated steam generation unit after a predetermined time has elapsed from the time when the operation for switching from the supply state to the standby state is performed.

In this way, it is possible to supply the superheated water vapor generation unit with water vapor having a lower temperature than the superheated water vapor generation unit within a predetermined time from the time when the operation of switching from the supply state to the standby state is performed, so that the superheated water vapor generation unit can be cooled. . In this way, the superheated water vapor generating section can be cooled to a set temperature in the standby state, thereby preventing damage to the device and the like.

According to the present invention having such a configuration, it is possible to generate superheated steam in a short period of time when it is desired to use superheated steam, and it is possible to suppress energy consumption in a standby state.

First, when the user operates the superheated water vapor generating device 100, for example, water in a container (not shown) is supplied to the water vapor generating unit 10.

At this time, the first heating temperature control unit 51 controls the first heating temperature so that the saturated water vapor generated by the water vapor generating unit 10 becomes a predetermined temperature. In this embodiment, the temperature of the first heating element 12 is set to the first temperature. A heating temperature.

Specifically, the first heating temperature control unit 51 obtains a measurement value from the first temperature sensor T1 provided on the first heating element 12 or the fourth temperature sensor T4 provided on the supply flow path L, and based on the measurement value, The magnitude of the AC voltage applied to the induction coil of the first heating means 11 is controlled, and the first heating temperature is controlled to, for example, 100 to 140 ° C.

In addition, in order to make the measured value closer to the temperature of the saturated water vapor, it is preferable that the first temperature sensor T1 is provided on the upper portion of the first heating element 12, the fluid outlet 12b, or the vicinity thereof.

In addition, the pressure regulating valve control unit 53 controls the valve opening degree of the pressure regulating valve 30 to The predetermined opening degree is such that the saturated water vapor generated by the water vapor generation unit 10 becomes a predetermined temperature or a predetermined pressure. Here, the pressure regulating valve control unit 53 obtains a measured value from a pressure sensor (not shown) provided in the supply flow path L, and controls the pressure regulating valve 30 to the predetermined opening degree based on the measured value. In this way, the saturated water vapor is maintained at a constant pressure on the downstream side (side of the superheated water vapor generation unit 20) of the pressure regulating valve 30.

Then, as described above, in a state where the water vapor generating unit 10 generates saturated water vapor, the on-off valve control unit 54 controls the on-off valve 40 to a state where the valve opening degree is zero, that is, a closed state. As described above, the superheated water vapor generating device 100 is in a standby state as a state where the water vapor generating unit 10 generates saturated water vapor and stops supplying the saturated water vapor.

In the standby state, the second heating temperature control unit 52 controls the second heating temperature to a temperature higher than the first heating temperature. In this embodiment, the temperature of the second heating element 22 is controlled to the second heating. temperature.

Specifically, in the standby state, the second heating temperature control unit 52 obtains a measurement value from the second temperature sensor T2 provided on the second heating element 22, and controls the induction coil of the second heating means 21 based on the measurement value. The magnitude of the AC voltage applied. In this way, the second heating temperature is controlled to the set temperature of the superheated steam generated by the superheated steam generation unit 20 or a temperature before and after it, and is controlled here to be, for example, 200 to 1200 ° C.

In the above-mentioned standby state, when a user inputs a switching signal from the outside using, for example, an input means, the on-off valve control unit 54 obtains the switching signal and switches the on-off valve 40 from a closed state to an open state. In this way, the superheated steam generating device 100 is switched from the standby state to the supply state, and starts The superheated water vapor generation unit 20 is supplied with saturated water vapor.

At this time, as shown in FIG. 3, the on-off valve control unit 54 controls the on-off valve 40 to gradually open so that the valve opening degree of the on-off valve 40 gradually increases from zero to a predetermined opening degree. In this way, from the switching timing of switching from the standby state to the supply state until the valve opening degree of the on-off valve 40 reaches a predetermined opening degree, an initial operation in which the supply amount of saturated steam is gradually increased is performed, and the valve opening degree reaches the predetermined opening degree. Starting at the time of normal operation, the supply of saturated water vapor is performed at a constant amount.

In the present embodiment, the second heating temperature control unit 52 controls the second heating temperature based on the measurement value of the second temperature sensor T2 within a predetermined time from the switching time as described above. On the other hand, the second heating temperature control unit 52 controls the second heating temperature based on the temperature of the superheated steam from the time when the predetermined time has elapsed.

To describe a specific embodiment of the control, for example, a third temperature sensor T3 for measuring the temperature of the superheated water vapor derived from the fluid outlet 22b is provided at or near the fluid outlet 22b. Then, the second heating temperature control unit 52 acquires the measurement value of the third temperature sensor T3 from the time when the predetermined time has elapsed, and controls the second heating temperature based on the measurement value.

Here, in the present embodiment, the predetermined time is set as a time from when the switching state is switched from the standby state to the supply state to when the superheated steam is discharged from the fluid outlet 22b of the second heating element 22.

Next, an operation for switching from the supply state to the standby state will be described.

The superheated steam generating device 100 according to the present embodiment starts from the time when the operation of switching from the supply state to the standby state is performed, and a predetermined time passes. After a while, the supply of saturated steam to the superheated steam generating unit 20 is stopped.

Here, the operation for switching from the supply state to the standby state refers to, for example, a user inputting a switching signal from the outside using an input means or the like, or outputting a predetermined time elapse signal indicating that the supply state has elapsed by a timer or the like.

More specifically, in the present embodiment, when the operation of switching from the supply state to the standby state is performed, the on-off valve control unit 54 obtains, for example, the switching signal and the predetermined time elapsed signal, and The on-off valve 40 is maintained in an open state for a predetermined time from the time. In this way, saturated water vapor is supplied from the water vapor generation unit 10 to the superheated water vapor generation unit 20 within the predetermined time.

Then, after the predetermined time has elapsed, the on-off valve control unit 54 switches the on-off valve 40 from the open state to the closed state, so that the superheated steam generator 100 switches from the supply state to the standby state.

According to the superheated water vapor generating device 100 of this embodiment having such a configuration, the water vapor generating unit 10 generates water vapor in a standby state in advance, so that it is possible to shorten the period of time during which the superheated water vapor is generated from the water and to generate the water vapor from the water. time. In this way, by switching from the standby state to the supply state, superheated steam can be generated in a shorter time than in the past.

In addition, since the supply of water vapor is stopped in the standby state, the water vapor generation unit 10 does not need to continue to generate water vapor, so that the energy consumed in the standby state can be suppressed.

The main reason for consuming energy in the standby state is to supply heat to the water vapor generation unit 10 and the superheated water vapor generation unit, for example, to supplement the heat emitted from the water vapor generation unit 10 and the superheated water vapor generation unit 20 through, for example, a heat insulator. 20 provides the energy of the heat level and the like.

In addition, in the standby state, the second heating temperature is controlled to be the temperature of the superheated steam generated by the superheated steam generating unit 20 or a temperature before and after it. Therefore, after the saturated steam is supplied to the superheated steam generating unit 20, the saturated steam immediately Began to be heated. This can further shorten the time for generating superheated steam.

On the other hand, since the second heating temperature is sufficiently higher than the temperature of the saturated water vapor, when a large amount of saturated water vapor flows into the superheated steam generation unit 20 rapidly, thermal shock is generated to the superheated steam generation unit 20. On the other hand, according to the superheated steam generating device 100 according to the present embodiment, the valve opening degree of the on-off valve 40 is controlled to gradually open from a state of zero to a predetermined degree of opening. Therefore, from the time of switching from the standby state to the supply state, The superheated steam generation unit 20 gradually supplies water vapor. In this way, superheated water vapor can be generated in a short time, and the above-mentioned thermal shock can be reduced.

Here, the second heating temperature control unit 52 according to the present embodiment controls the second temperature sensor T2 based on the measurement value of the second temperature sensor T2 within a predetermined time from the time when the standby state is switched to the supply state and when the superheated steam is discharged. Heating temperature. The second heating temperature is controlled based on the measurement value of the third temperature sensor T3 from the time when the predetermined time has elapsed.

In this way, although there is a time difference from the time when the standby state is switched to the supply state until the superheated water vapor is generated, the second heating temperature control unit 52 of this embodiment can control the second heating temperature with high accuracy in accordance with the time difference.

In addition, since the pressure regulating valve 30 regulates the saturated water vapor supplied to the superheated steam generation unit 20 to a predetermined pressure, the saturated water vapor can be stably supplied to the superheated steam generation unit 20 in the supply state. In this way, the superheated steam discharged from the fluid outlet of the superheated steam generation unit 20 also has a stable flow rate, and the user can use the stable superheated steam.

In addition, since the saturated water vapor is supplied from the water vapor generating unit 10 to the superheated water vapor generating unit 20 within a predetermined time from the time when the operation of switching from the supply state to the standby state is performed, the high temperature can be maintained in the supply state. After the superheated steam generating unit 20 has cooled, it switches to the standby state. In this way, by cooling the superheated steam generation unit 20 to the set temperature in the standby state, damage to the superheated steam generation device 100 and the like can be prevented.

The present invention is not limited to the above-mentioned embodiments.

For example, in the above embodiment, each heating means heats each heating element by an induction heating method, but each heating means may heat each heating element by a current heating method.

Moreover, although the water vapor | steam generating part of the said embodiment heats water and produces | generates saturated water vapor | steam, you may generate superheated water vapor | steam whose temperature is slightly higher than saturated water vapor | steam.

In this case, the superheated steam generation unit may further heat the superheated steam generated at a temperature slightly higher than the saturated steam generated by the steam generation unit to generate superheated steam at a predetermined temperature.

Furthermore, the first and second heating temperature control units of the above-mentioned embodiment control the temperatures of the first and second heating elements to the first and second heating temperatures, but the first and second heating may be input from the outside, for example. Means The set temperature and the like are controlled as the first and second heating temperatures.

In addition, the pressure regulating valve control unit of the above embodiment controls the valve opening degree of the pressure regulating valve to a predetermined opening degree so that saturated water vapor becomes a predetermined pressure, but the valve opening degree of the pressure regulating valve may be controlled to a predetermined opening degree. , So that, for example, the temperature of saturated water vapor becomes a predetermined temperature.

In this case, the pressure regulating valve control unit may obtain the measured value of the first temperature sensor T1 as the temperature of the saturated water vapor. As shown in FIG. 4, it may also obtain a fourth temperature sensor provided on the supply passage L. The measured value of T4 is taken as the temperature of saturated water vapor.

In addition, in the above-mentioned embodiment, the control device 50 controls the pressure regulating valve 30 and the on-off valve 40 respectively. However, as shown in FIG. Valve 30.

As specific control content, the control device 50 controls the pressure regulating valve 30 to gradually increase the pressure of the saturated water vapor supplied from the water vapor generation unit 10 to the superheated water vapor generation unit 20, thereby switching from the standby state to the supply state.

According to the above-mentioned structure, since the pressure regulating valve 30 has a function of opening and closing and regulating the pressure, the number of valves provided in the supply passage L can be one, and the cost can be reduced.

In addition, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.
